VP9 hardware decoding broken in 17.10, displaying corrupted images in frames while playing videos

[Prasad Murthy]

OS version: Ubuntu 18.04 beta rc
Hardware: Intel core i5 7400 (Kaby lake processor)
with Intel HD graphics 630 supporting VP9 10-bit and 8-bit video decoding.

In version 1.8.x of the driver the VP9 decoding is broken, the corresponding upstream patch got into 2.0.0. But since VP9 profiles are missing in version 2.0.0 driver in Ubuntu 18.04, hardware acceleration is absent, so high cpu and power usage. The buggy driver 1.8.x is used in the vlc snap too and snap developers doubt the driver version in snap will be upgraded.

* VP9 decoding broken in 17.10
* VP9 decoding broken in snap packages

Either driver version has to be updated to 2.1.0 or at-least cherry pick a one line patch to current Ubuntu core snap, a link for which I will mention below.

Upstream driver patch: https://github.com/intel/intel-vaapi-driver/commit/9d66570032fb02b1e79a883af7697b035d700a8e

Upstream bug report: https://github.com/intel/intel-vaapi-driver/issues/297

In any way kindly support VP9 hardware decoding via supported Intel hardwares in in 17.10(by backporting driver v2.1.0/cherry picking upsteam patch) or atleast via updated snap core/apps.

Fixed with the 2.1 upload as well.

Any chance this gets fixed for Xenial?
